How to test a car battery?
A measuring device which can only measure the state of charge of the battery is suitable to test a conventional car battery. In an ideal case, an open circuit voltage of about 12.8 V is measured with a Multimeter. If the voltage falls below 12.4 V, the battery should be recharged as soon as possible.
How do you check a car battery at a garage?
At a garage – or with a mobile mechanic – a handheld battery tester can be used. This is a tool specifically designed to check the health of your car battery. It usually provides a quick reading on the battery’s charge and health. It will state whether it is weak or needs replacement.
Should you check your car battery's health?
When it comes to car maintenance, checking your car battery’s health is something that is often overlooked. The health of your car battery is crucial for ensuring the peace of mind of a car that reliably starts and won’t leave you stranded.
What does a battery test tell you?
However, a voltage test alone doesn’t give you the full story of a battery’s condition; it only tells you its State of Charge (SOC). A modern battery tester, on the other hand, can tell you the battery’s State of Health (SOH), which is a much more accurate predictor of the battery’s overall condition.
How do you test a start-stop battery?
When testing a start-stop battery, not only the state of charge (also known as the “SOC”), but also the state of health (“SOH”) of the battery are important. While the SOC can be simply determined with a voltage measurement, a complex test procedure is required to test the SOH, in order to make a reliable statement about the state of the battery.
When should a car battery be tested?
A regular battery check by a specialist workshop is therefore advisable in order to detect an imminent battery failure before a final breakdown occurs. A measuring device which can only measure the state of charge of the battery is suitable to test a conventional car battery.
